#MERGING MULTIPLE IMAGES HDR EFEX PRO PRO#
To apply HDR effects to a single image, you’ll first need to convert it to 32-bit color (the HDR Efex Pro option under “Filters” will be grayed out until you do this). A composite image will automatically launch in the HDR Efex Pro interface. To merge multiple exposures into a single HDR image with Photoshop as your host application (the exact steps vary depending on your host software), go to File > Automate > HDR Efex Pro, and select the files. Nik HDR Efex Pro is compatible with Adobe Photoshop, Bridge and Lightroom, and Apple Aperture. You can use HDR Efex Pro to enhance the apparent dynamic range of a single image, or use it with multiple images at varied exposure values for true dynamic range expansion.

If you’ve used Nik software before, the interface will be immediately familiar, complete with Nik’s Control Points with U Point technology for localized adjustments. HDR Efex Pro's advanced tone-mapping algorithm allows you to increase the dynamic range of one. Even though many HDR photos require multiple exposures, there are times when you only have one image and want to achieve the HDR look. HDR Efex Pro does all the calculations and work to combine multiple exposures to create dramatic HDR photos that look natural and stunning. Setting it apart are multiple tone-mapping algorithms, from photo-realistic to otherworldly, giving you broad creative latitude in an easy-to-use tool. Multiple photos of the same subject taken at different exposures with a camera's bracketing function create great HDR images. HDR imaging has emerged as a serious tool for photographers, and this new application from Nik is one of the most robust solutions we’ve used.
